A South African doctor has developed a new anti-rape female condom that has been unveiled in time for the World Cup.

The Rape-aXe was invented by Dr Sonnet Ehlers, who plans to distribute 30,000 of the devices during the course of the World Cup, CNN reports.

The latex condom is inserted by the woman like a tampon, and features jagged rows of teeth-like hooks that latch onto an attacker’s penis upon penetration.

Once attached, only a doctor can remove the Rape-aXe and Ehlers hopes authorities will be on the scene during any potential removals.

Possible problems with this plan:

a: One of the major danger in being raped is that they will kill you afterwards, a condom won’t help that
b: The old “hooks in the penis” thing is probably only likely to enrage a rapist, making them more likely to kill you in any case
c: By the time this does anything, you’ve already been raped. It might help to catch the guy who did it but in most cases of rape that is rarely the issue anyway.
